Application filed February 10, 1915.

in the means for connecting the beams to the frame andpermit vertical and also lateral swinging movement of the beams and the cultivators or other earth working implements carried thereby.

Another object is to effect improvements in the means for connecting the cultivator,

standards to the beams for simultaneous pivotal movement and to provide a single break pin for each gang or set of cultivators.

In the accompanying drawings: Figure 1 is a side elevation of a wheeled cultivator constructed in accordance with my invention, Fig. 2 is a plan of the same. Fig. 3 is a rear elevation of the same. Fig. 4 is a vertical longitudinal sectional view of the same. Fig. 5 is a detail elevation of one of the beams, its cultivator standards and break pin.

In accordance with my invention the main frame 1 of the wheeled cultivator comprises a pair of members 2 each of which is formed from a single bar of metal the rear end of which is curved downwardly and forwardly as at 3. The bars 2 are each provided at suitable distances from their front ends with offset portions 45 and their front portions are in mutual contact and are secured together by means of a rivet or other suitable device 6. The front portions of the bars form a tongue and the rear portions thereof form the sides of the frame. Each bar is also provided with a curved member 7 the lower rear end of which is in overlapping relation to the lower front end of the curved portion 3, the upper ends of the said members 7 being bolted as at 8 to the bars 2 at points between the offsets 45. A cross bar 8' which is arranged on the upper sides of the bars 2 has its ends, which are downturned, secured to said bars Specification of Letters Patent.

at points in rear of the oifsets 4. A cross bar 9 also connects said bars 2 at points in rear of the offsets 5, is arranged on the under side of said bars and has its upturned ends bolted thereto. A doubletree 10 is secured to the cross bar 9 by a clip 11 and bolt 12, the usual swingletreebeing attached to the ends of the doubletree. Each side of the main frame also has a vertically arranged bar 13, the upper end of which is bolted to one of the side bars 2 and its lower end bein secured on the outer side of the member by a bolt 14 which also forms a stub axle and spindle. Wheels 15 are mounted on the spindles of the stub axles and serve to support the frame. An arch bar 16 connects the rear portions 3 of the bars 2 and carries a seat 17 for the driver. The frame thus constructed is extremely cheap and simple and is light, strong and,

durable.

A pair of beams 18 are arranged between the sides of the cultivator frame and each beam has its front end pivotally connected as at 19 to a clip 20 which is secured to the lower end of a lever bar 21. The pivots 19 of the beams are arranged in vertical planes so that the beams are adapted to be swung laterally and the lever bars 21 are pivotally connected to the inner sides of the bars 2, their pivots 22 being horizontally arranged so that said lever bars together with the beams are adapted to swing in vertical planes and hence the beams and the cultivator shovels and other earth working implements which they carry are mounted for both vertical and transverse movement. The lever bars 21 extend above the bars 2 and their upper ends are connected to the rear ends of coiled retractile springs, the front ends of the spring being connected to the cross bar 8. Said springs exert their tension to draw the upper ends of the lever bars forwardly and hence serve to normally raise the beams and the implements which they carry. To enable the beams to be depressed at their rear ends to cause their implements to'work in the earth I provide each beam with a lever arm 24. Said lever arms are adapted to be operated by the drivers feet and when the levers are raised the driver may readily move the lever arms outwardly and cause them to be engaged with hooks 25 with which the bars 2 are provided and which depend therefrom, said hooks thus serving to support the beams and their earth working implements in raised position.

Each beam has a brace bar 26 on its outer side and also carries a series of standards 27 which are pivotally connected thereto as as 28 and the upper ends of which extend above the beam. The standards of each series have their upper ends connected together by a link rod 29 which is pivotally connected thereto as at 30 and hence all the standards of each series are adapted to turn in unison. One standard of each series is normally held in operated position by a break pin 31. The usual cultivator shovels or other suitable earth working implements are attached to the lower ends of the standards. When one of them encounters an obstruction such as a stone or root the break pin is broken and all'the standards of that series turn simultaneously thus enabling all of the implements to safely pass over the 0bstruction and avoid injury to the plows.

While I have herein shown and described a preferred form of my invention I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of the invention and Within the scope of the appended claims.

Having thus described my invention, I claim '1. In a Wheeled-cultivator a frame comprising a pair of bars having their front ends connected together and having their rear ends spaced apart, said bars having downwardly and forwardly curved rear portions, curved bars connecting the lower ends of said rear portions to the said side bars, vertical portions connecting said side bars and curved portions and stub axles connecting the lower ends of said vertical bars, side bars and curved bar together and provided with spindles for supporting wheels.

2. In a wheeled cultivator a frame coniprising a pair of bars having their front ends connected together and having their rear ends spaced apart, said bars having downwardly and forwardly curved rear portions, curved bars connecting the lower ends of said rear portions to the said side bars, vertical portions connecting said side bars and curved portions and stub axles connecting the lower end of said vertical bars, side bars and curved bar together and provided with spindles for supporting wheels, a cross bar connecting said side bars and arranged at a point between said vertical bars and the front ends of said curved bars and a doubletree connected to said cross bar.

In testimony whereof I aflix my signature in presence of two witnesses.
